Techniques of culturing Tenebrio Molitor

Tenebrio Molitor, also known as bread beetle, belongs to Coleoptera, Tenebrionidae and Tenebrionidae in insect taxonomy. Originally from North America, it was introduced to China from the Soviet Union in the 1950s. Tenebrio Molitor dry products contain 30% fat and more than 50% protein. In addition, they also contain major elements such as phosphorus, potassium, iron, sodium, aluminum and a variety of trace elements. Because the dried Tenebrio Molitor larva contains about 40% protein, the pupa contains 57%, and the adult contains 60%, it is known as the "protein feed treasure house". Let's take a look at the techniques of cultivating yellow powder insects.

First of all, after obtaining the species, after careful screening, the individuals with large size, neatness, strong vitality and bright color were selected and fed in a special pot. Ordinary washbasin-sized containers raise larvae 0.3-0.6 kg. Put feed in the basin, such as wheat bran, corn meal, etc., and at the same time put larvae and insects. The feed is 10: 20% of insect weight and 3: 5 days. After the insects have finished eating the feed, the insect feces are screened out with a 60-mesh sieve. Continue to feed. Properly add some vegetables, fruits, peels and other hydrated feed.

Secondly, when the larvae pupate, the pupae are picked out and stored separately in time. After 8 days and 15 days, the pupae emerged into adults. Spread a newspaper at the bottom of the basin or box, then spread a layer of fine feed about 1 cm thick on the paper, and put the feathered adults on the feed. At 25 ℃, the adults began to mate and lay eggs after emergence for about 6 days. Tenebrio Molitor is a gregarious insect, which must have a certain population density for mating and laying eggs. Adults are fed with better concentrate feed during the spawning period, in addition to mixed feed plus multivitamins, plus an appropriate amount of water-bearing feed, such as vegetable leaves and melon peel.

Thirdly, when the adults lay eggs, they extend the ovipositor under the feed and lay the eggs on the paper. 3. After 5 days, the egg paper is full of eggs, so the new egg paper should be replaced. The removed eggs are collected in paper and placed in a basin on the same date for hatching. It can hatch in 6-9 days at 24: 34 ℃. The newly hatched larvae are very soft and soft. Try not to touch them with your hands so as not to hurt them.

Finally, the hatched larvae were reared together. After 15-20 days, the feed in the basin was basically finished, and the insect feces could be screened for the first time. The insect feces were screened with a 60-mesh screen, and then the insect feces were screened every 3-5 days, and the feed was fed at the same time, and the feed input was eaten in 3-5 days.
